It is recommended to use ColorTouch Assistant software to initialize an SD card and upgrade to the latest firmware.

Besides upgrading to the latest firmware, with ColorTouch Assistant you can import and edit your photos from a drive on your computer, prepare them for use as the thermostat's screen saver, or choose a photo for a custom wallpaper background. ColorTouch Assistant allows you to configure your time period schedule and adjust your thermostat's installation settings from the comfort of your laptop or desktop computer.
